Abstract: A hover button sensor unit, comprising: a power supply circuit (5-1), a capacitive sensor, a capacitance-to-digital conversion circuit (3), a control module, an acousto-optic feedback control circuit (5-3), and a communication circuit (5-2); The capacitive sensor is a convex structural arrangement of a central electrode (1-1) and a peripheral electrode (1-2).

Abstract: The present application relates to a sensor with a time-sharing regional shielding function and a robot. The sensor comprises a plurality of sensor units, each of which comprises regions contained in four multifunctional layers. Four parallel-plate capacitors are contained in the multifunctional layers. The multifunctional layers realize the regional shielding function through the time-sharing switching of analog switches and the control of a bus.

Abstract: The present application relates to a touch sensor with multifunctional layers and an intelligent robot. The touch sensor comprises a plurality of sensor units. Each of the sensor units comprises regions contained in four multifunctional layers. The first multifunctional layer and the third multifunctional layer are higher than the second multifunctional layer and the fourth multifunctional later, and the distance from the center of the first multifunctional layer to the center of the third multifunctional layer is greater than the distance from the center of the second multifunctional layer to the center of the fourth multifunctional layer. The first multifunctional layer and the third multifunctional layer form a capacitor C1, and the second multifunctional layer and the fourth multifunctional layer form a capacitor C2.
